Machine body assembly and clothes dryer

The invention relates to a machine body assembly and a clothes dryer. The machine body assembly comprises a machine shell. At least one side of the machine shell in the first direction sinks inwards in the first direction to form a sunken structure, and the sunken structure is provided with an air inlet. Wherein the first direction intersects with the height direction of the machine body assembly. According to the machine body assembly, the side face of the machine shell sinks inwards to form the inwards-sunken structure, and the air inlet used for air inlet of the air channel assembly is formed in the inwards-sunken structure. Thus, the air inlet is formed in the sunken structure, the space of the side face of the machine body assembly can be fully utilized, the air inlet area is increased, the air inlet amount is increased, and then the clothes drying efficiency is improved. In addition, due to the fact that the sunken structure is formed on the machine shell in an embedded mode, the waterproof effect can b
